Mm just very small test to see how well BlendMode based Metaballs effect will work. Well works worser then bitmalFilter based I used before. And a lot worser. Looks little bit more interesting tough
Only 100 balls and no collisions. May lagg a little.
It seems that BlendingModes take a lot of calculations and it is not that hard to see why. Making full screen post processing to achieve similar effects becomes a lot more effective with raise of count of objects.
